AMENTUM E&C LIMITED
AMENTUM E&C LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 04967961, and its current status with Companies House is active. The company was incorporated on 18 November 2003 and lists its registered address as Warrington, United Kingdom. 2 shareholders are on record for AMENTUM E&C LIMITED, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.
